For some glamorous sweethearts, it was the first time they were attending the awards as a married couple – including Benedict and Sophie.
One of the most watched men of the night will be Eddie Redmayne, who is in the running for Best Actor in a Leading Role for his stellar performance in The Theory of Everything. The 33-year-old was joined by his new wife Hannah Bagshawe, who he married in a recent winter wonderland wedding in Somerset.
The antiques dealer kept it simple in a black gown with a gold embroidered belt and high neckline, while Eddie looked sharp in a midnight blue tuxedo.
Wild star Reese Witherspoon, who has been shortlisted for Actress in a Leading Role, also turned heads for her flawless style. With her husband Jim Toth as her date, the blonde glamazon took people’s breath away in a Tom Ford off-the-shoulder gown.
Chrissy Teigen also turned heads on the red carpet, as she lit up the evening in a glittering Zuhair Murad full-length gown that featured a plunging neckline. The model arrived with her musician husband John Legend, who was performing on the night.
New mom Zoe Saldana, who gave birth a mere three months ago, flaunted her incredible post-pregnancy body in a pale pink gown. The actress was accompanied by her husband and father of her twins Marco Perego.
Also walking the incredible 500 foot long red carpet were Patricia Arquette and her boyfriend Eric White, who were one of the first couples to arrive. The pair were joined by the actress’ family and stopping to chat before the ceremony, Patricia, who has been nominated for Best Actress in a Supporting Role, couldn’t hide her excitement.
Nominee Robert Duvall and his wife Luciana, and Jennifer Aniston and Justin Theroux among other A-listers, all flaunted their romance on the red carpet.
